Abstract: Infrastructure electronics equipment incorporates infrastructure Local-Site Transports (LSTs). LSTs convey payload sampled signals over imperfect electromagnetic (EM) pathways whose physical properties are usually unknown when the equipment (e.g., Cameras, Displays, Set-Top Boxes) is manufactured. Prior LSTs hedge against EM pathway degradation in several ways: requiring high-quality cables (e.g., HDMI); restricting transmission distance, (e.g., HDMI); and/or reducing quality, via compression, to extend transmission distance somewhat (e.g., Ethernet). The subject of this disclosure is an infrastructure LST for sampled signals that causes the physical errors inevitably arising from propagation of sensory payloads over imperfect EM pathways to manifest in a perceptually benign manner, leveraging legacy infrastructure and reducing costs to achieve a favorable ratio of fidelity to transmission distance.

Abstract: A regen node is described. The regen node includes a coherent receiver, a control module and a coherent transmitter. The coherent receiver has circuitry to convert a first optical signal received from an upstream node in an optical layer of an optical network to a first digital data stream in a digital layer having a first FEC frame and a data traffic. The control module extracts a first fault signal from the first FEC frame; generates a second fault signal based at least in part on the first fault signal; and encodes the second fault signal within a second FEC frame with the data traffic into a second digital data stream on the digital layer. The coherent transmitter has circuitry to convert the second digital data stream into a second optical signal on the optical layer and to transmit the second optical signal to a downstream node.

Abstract: A multi-level optical signal is sampled to generate an eye diagram. The signal can be adjusted when eyes in the eye diagram have different heights. More specifically, a first value is determined, and the height of a first eye is adjusted using the first value. The first value is multiplied by a stored factor to produce a second value, and the height of a second eye is adjusted using the second value, and so on for other eyes. As a result, eye heights are the same. Similarly, optical power levels of the signal can be adjusted when the levels are not equally spaced. As a result, the optical power levels are equally spaced.

Abstract: A stop assembly may include a first portion configured to selectively operably engage a track of a tool and a stop portion operably engaged with the first portion configured to releasably engage a workpiece. The stop portion may be pivotable between a disengaged position and an engaged position relative to the first portion. The stop portion may move in a rotational direction toward the first portion when moving from the disengaged position to the engaged position. A method of use may include pivoting a stop portion of a stop assembly, about a pivot axis defined by a pivot shaft of the stop assembly, to an engaged position such that the stop portion moves in a rotational direction toward a first portion of the stop assembly.

Abstract: The invention provides an automatic stop method and device for a can opener. When a first rotation frequency of a bearing in a first preset time is smaller than a second rotation frequency of the bearing in a subsequent second preset time in the process of opening a can by a can opener blade and a difference between the second and first frequency reaches a preset value, it is determined that repeated cutting occurs, and the blade will be stopped in time to avoid problems caused by repeated cutting. Meanwhile, mean values of multiple data acquired within the first and second preset time are calculated, avoiding the problems of an excessively high and long instant processing burden of one time of data acquisition and errors caused by data acquired once, improving the timeliness and accuracy of the first and second frequency, and can opening can be controlled more accurately.

Abstract: Techniques and mechanisms for verifying integrity of components within a management component transport protocol (MCTP) server system to detect man-in-the-middle (MITM) attacks and preventing data loss upon detection of MITM attacks. For example, a controller may perform an endpoint discovery process and authenticate endpoints within a rack server system. The controller may send requests to endpoints based on user actions and if no response is received from a particular endpoint, the controller may determine there is a MITM attack and block traffic to the particular endpoint. Additionally, the controller may periodically request measurements from endpoints that are related to the code and configuration area of the endpoints. If the received measurements from a particular endpoint do not match expected values, the controller may determine there is a MITM attack and block traffic to the particular endpoint.

Abstract: A network apparatus maintains a data repository comprising network traffic data related to a plurality of user devices, the network traffic data being collected from a plurality of Network Service Providers (NSPs). A subset of the plurality of user devices are detected to be communicating with one or more same endpoint devices based on analysing the network traffic data. A number of historical connections between each user device of the subset of the plurality of user devices and the one or more endpoint devices is determined based on analysing historical connection data maintained in the data repository, and in response to detecting that the number of historical connections between the subset of the plurality of user devices and the one or more endpoint devices exceeds a predetermined threshold, the one or more endpoint devices are identified as a suspected botnet.
